Abstract: Various embodiments include a substrate having including a first doped region and a second doped region located on a first side of the substrate, and a third doped region and a fourth doped region located on a second side of the substrate, an insulation layer overlying the substrate, a gate layer overlying the insulation layer, a barrier layer overlying the gate layer, and an electrode layer overlying the barrier layer. The first and third doped regions may be located on a first side of the gate layer. The second and fourth doped regions may be located on a second side of the gate layer. The first and third doped regions may be source and drain regions of a first transistor. The second and fourth doped regions may be source and drain regions of a second transistor. The gate layer may include a gate segment to couple to a third transistor. Other embodiments are disclosed.

Abstract: A semiconductor device includes a cross diffusion barrier layer sandwiched between a gate layer and an electrode layer. The gate layer has a first gate portion of doped polysilicon of first conductivity type adjacent to a second gate portion doped polysilicon of second conductivity type. The cross diffusion barrier layer includes a combination of silicon and nitrogen. The cross diffusion barrier layer adequately prevents cross diffusion between the first and second gate portions while causing no substantial increase in the resistance of the gate layer.
